💡 Pro Tips for SAM 3 - 3D Body

★

Capture Full Body for Best Results SAM 3 - 3D Body performs best when the entire human figure is visible from head to toe. Avoid cropped images where limbs extend beyond the frame. Position subjects in a neutral standing pose with arms slightly away from the body to ensure accurate limb detection. Good lighting and high contrast between the subject and background improve segmentation quality. If you're working with partial body shots, consider Meshy v6 Image to 3D for more flexible object reconstruction.

★

Use Binary Masks for Complex Backgrounds When photographing people against busy or cluttered backgrounds, provide a binary mask to guide the model's segmentation. Create a simple black-and-white image where white pixels represent the person and black pixels represent everything else. This optional mask dramatically improves accuracy in challenging scenes with similar colors or overlapping objects. Most image editing tools can generate these masks quickly using selection tools. The mask upload is found in the advanced options section of the input form.

★

Process Multiple People Efficiently SAM 3 - 3D Body automatically detects and generates separate meshes for each person in your image. To maximize this feature, ensure adequate spacing between subjects and avoid heavy overlap. The model exports individual PLY files per person, making it easy to import each figure separately into your 3D software. This multi-subject capability is particularly valuable for crowd analysis, group animation projects, or sports team modeling where you need distinct 3D representations of each athlete or performer.

★

Enable Keypoints for Motion Analysis The include_3d_keypoints option adds visible sphere markers at critical body joints in your GLB output. These markers are invaluable for biomechanics research, sports performance analysis, and animation rigging. Keypoints clearly indicate shoulder, elbow, hip, knee, and ankle positions in 3D space, providing precise reference data for motion capture workflows or posture assessment. If you need text-based 3D generation instead, try Hunyuan 3.1 Pro Text to 3D for creating custom body poses from descriptions.

★

Optimize Image Resolution and Clarity Upload images at least 1024×1024 pixels for optimal reconstruction quality. Higher resolution inputs capture more body detail, resulting in smoother meshes and more accurate pose estimation. Ensure the subject occupies a significant portion of the frame—small figures in distant shots may lose detail. Use sharp, well-focused images; motion blur or soft focus can degrade the model's ability to detect body contours. For general object-to-3D conversion with different requirements, explore Meshy v6 Image to 3D.

★

Export Settings for Your Workflow GLB files are ideal for web-based 3D viewers, game engines like Unity or Unreal, and AR applications. PLY meshes offer broader compatibility with professional 3D software such as Blender, Maya, or ZBrush. Enable export_meshes if you need individual files per person for separate manipulation. The metadata JSON includes detailed keypoint coordinates, useful for programmatic analysis or custom visualization tools. Choose your export format based on your downstream pipeline to minimize conversion steps and preserve model fidelity.
